The new enhanced Catalyst 6500 16-port GBIC-based Gigabit Ethernet Module provides a cost-effective and flexible approach to deploying gigabit Ethernet in the backbone of the network as well as server-farms. Supporting the GBIC form factor that can be used with Fiber or Copper installations, this module also offers higher density coarse wave division multiplexing (CWDM) and ZX-based GBIC deployments when used in the Catalyst 6500 multilayer switch series or Cisco 7600 Internet Router Series.
